TITLE

Revision of spindle software for αi SP,
βi SVSP TYPE C (9D60/C)
B-65280E/05-02
4. Measurable data at the Graph Window for SERVO GUIDE
In case of α
i SP, βi SVSP TYPE C, measurable data at the Graph Window for SERVO GUIDE is as
follows. The specification of data is different from α
i SP which uses velocity sensor, because αi SP, βi
SVSP TYPE C is applied to spindle motor without velocity sensor.
Data for current and velocity control
SPEED (Motor speed, 4096=1min
-1
)
Estimated motor speed.
Maximum resolution of this data is "4096 = 1 min
-1
" at shift value="0".
In default setting, shift value is "-12" and the resolution is "1 = 1 min
-1
".
INORM (Amplitude of motor current)
Amplitude of actual motor current.
Set Conv. Coef. and Conv. Base according to following procedure to convert the unit to "Ap".
Unit : select A(p)
Conv Coef. : set "640 x Ga / ICNV"
Conv. Base : set 1024
ICNV (current conversion constant) : Setting of Prm.No.4110
Ga (current detecting gain) : Coefficient for amplifier model. See following table.

TCMD (Torque command, 16384=100%)
"16384(100%)" is maximum torque command.
VCMD (Velocity command, 4096=1min
-1
)
Velocity command for actual motor speed control.
Maximum resolution of this data is "4096 = 1 min
-1
" at shift value="0".
In default setting, shift value is "-12" and the resolution is "1 = 1 min
-1
".
VERR (Velocity error, 4096=1min
-1
)
Difference data between velocity command and (estimated) motor speed (VCMD-SPEED).
Maximum resolution of this data is "4096 = 1 min
-1
" at shift value="0".
In default setting, shift value is "-12" and the resolution is "1 = 1 min
-1
".
